Bypass the Bose Amp in a Nissan For Better Sound

[@milesbachelor8747]

Good job getting in there figuring it out. Saving big money. The Bose deck and factory amp have a weird relationship I’d be scared to eff with.

[@beakerwsw]

If you dont use the preouts on the head unit and try to wire up the regular speaker outs you'll run into massive clipping. The highest voltage outputs for RCA's to the bose amp is 4v. Metra makes a bose integration connector for nissans that uses the RCA's instead of stereo line out.

[@TheKeymaster316]

Good to know! I’ve since sold the car but that will be helpful for other folks. Thanks!

[@stevetaylor5203]

So reusing the amp isn't a good idea I took one out of a totaled Nissan we had was planning on installing it in one of our trucks one is a single cab 90 model and the other a expedition 97 model so I thinking I should get a better amp now after seeing this

[@TheKeymaster316]

If you’re going with an aftermarket radio, absolutely. If you are keeping everything stock, you would be fine. But if you’re upgrading the radio and door speakers, you definitely want to bypass this amp.

[@JenningsWest]

Damn you got an awesome deal on that I have to take out eBay for myself

[@StefanMoIyneux]

I've got an '18 with bose. If I'm using a loc would I just tap into the rear deck going to the amp ? Trying to add a sub that won't be on boses crossovers

[@TheKeymaster316]

I never tried adding a sub with the stock radio. You definitely don’t want to tap into the amp side for your LOC. I would tap into the speaker wires right behind the deck to install the LOC and see how that works.

Que color es el cable que envia la señal al amplificador para que encienda?? Gracias

[@Mkikorodriguez]

So I just got an 05 ser your video has been very helpful thank you. For some reason my speakers still sound bad any tips or suggestions.

[@TheKeymaster316]

Did you install an aftermarket head unit? I did end up putting some JBL’s in the front doors and that improved the sound as well.

[@karanjeetsinghgodara3339]

I connected 2 subs through line out converter, it worked out but after couple of days I started feeling same distortion in bass and when I turned my amp off to check stock rear speakers and I got confirmation that something fucked up but I guess I need to do all this job and will take my whole, So as I've stock head unit do you've any other way to do this bypass..? And what are your thoughts on bypass harnesses, will you recommend those or not ?

[@TheKeymaster316]

I’ll be honest, we sold this car about 3 years ago, but I replaced the head unit several years before selling it. The best way I knew to get good sound from the car after upgrading the head unit and speakers was to bypass that amp in the trunk. Ultimately, you’d want to run every speaker wire to every speaker from scratch, but that can be very time consuming. The one thing about that stock head unit is that it has something built in that affects the volume at different times while driving, which I believe is one of the reasons for the adverse sound when you start upgrading the stereo system. So for me, if I ever had one of these cars again, the head unit would be the first thing I’d replace.

[@SLiveForTheMoment]

Have a 2006 Nissan Sentra 1.8S stock system Recently amp keep blowing fuse Was tryna replace the amp but someone told me the wiring would be different wouldn't be plug and play any recommendations?

[@TheKeymaster316]

I’ll be honest, I’m not familiar with the Sentra’s. I sold this car last year so I had to wire this amp back up, since I took the aftermarket one out before selling it.

[@SeanA88]

I wish I could find new Clarion NDSS speakers. I owned an 04 before my 06 and those speakers were in great condition. I had a lot of people ask me if I had a small subwoofer. I could try a junkyard but most are probably junk

[@SeanA88]

@@gavinmcclure8047 my set in my 06 still sound really good, I usually keep the bass at 2. I think they're way better than bose and one of the best stock speakers I've ever heard

[@Sinister_187]

Was it cutting out wen volume was high ?

[@TheKeymaster316]

It didn’t cut out but it was distorted. You could tell it didn’t sound like it should have.

[@Sinister_187]

Ok thnx got i35 2003 but wen I put it too high the radio cut out ima put bigger fuse & check if it works if not is the stock amp for the original stock speakers

[@TheKeymaster316]

@@Sinister_187 well, with the different Ohm load on the stock speakers, it could be an issue. I never cranked mine up to crazy loud volumes, usually just half way or slightly more.

[@youclandex7]

Just connect the amp to the low power output and sound greate

[@youclandex7]

@@curtisjohnson1140 low power output of the stereo, the RCA's

[@offthealleyengineering3974]

Anything I should know about replacing the amp want to also replace the door speakers for something more clearer and louder.

[@TheKeymaster316]

I found some used JBL’s on eBay. I think they were store models, they were in great shape and were very reasonable. I just push the door speakers with the radio. It does the job for me but you could get you a 5 channel amp to push the door speakers and a sub. Rockville sells a cheap one that I have in my other car that only cost $150. You can find them on eBay or Amazon.

[@raulflores3004]

Hello, good afternoon Hey you'll have a full diagram photo of both harnesses?? I've already looked at the link you put in and I don't wrap it

[@marshallvines9922]

I want to put in a double din kenwood stereo with a new amp. Do you run the regular output from the stereo or the pre amp output to the amp? Also which plastic radio trim cover did you use to change out the stereo from stock to aftermarket?

[@TheKeymaster316]

I used the low-level RCA out from the radio to my Alpine amp. As far as trim cover, I got mine off of Amazon. It’s a Scosche NN1660B and is currently $6.99.

[@dilwead169]

Did you get a chance to check out the video I made showing you how to play those dark forces 2 levels ? If so have you got a chance to try it out ? Just curious !

[@TheKeymaster316]

Not yet, I'll check them out and let you know. Thanks!

Would this be the same wiring diagram to use for '03 infiniti g35 sedan? Thanks!

[@TheKeymaster316]

Lauren Christina possible but not 100% sure. I know the cars have a lot of similarities

[@ReneSalvador]

so what exactly is powering your speakers? is it the head unit?

[@TheKeymaster316]

René Salvador, yes, the head unit is powering the door and pillar speakers. I have a mono Alpine amp powering the speaker box in the trunk. I have much better sound after bypassing the Bose amp in the trunk, especially at higher volumes.

[@Andrew-yw8vz]

How did you run your speakers to your head unit, instead of the amp? What did you do?

[@TheKeymaster316]

Just A Guy I’ll double check for sure, but basically once you know what color wires go to what, you can bypass the amp and just splice the wires going into the amp to the wires coming out of the amp.

[@lowlifespore8993]

Where can I buy the wires and stuff for this amplifier ? I have the amp with no wires ...

[@TheKeymaster316]

You’re looking for the Bose wiring? Best bet is the junkyard and try to find a car that has the Bose system. Probably wouldn’t charge you hardly anything for it.

[@JesusMartinez-fg1cq]

Does the amp have to be connected

[@TheKeymaster316]

I don't think so. You're basically just bypassing the amp and sending the signal from the aftermarket head unit straight to the speakers. I just sold the car about 2 months ago and had to re-splice all of the wires back because I put the factory head unit back in.

[@JesusMartinez-fg1cq]

So I also have to hard wire the connection in the back of the head unit

[@TheKeymaster316]

@@JesusMartinez-fg1cq I used an aftermarket harness to tie my Pioneer head unit to the factory wiring, so yes.

i bought a used nissan a while back and they already deleted the amp....but only my front right speaker works and if i hit a bump the front tweeters will be the only thing working.

[@TheKeymaster316]

Sounds like they may have only wired the front speakers up. Look at my reply for David Tarrant in the comments. I attached a link to the wiring diagram for my car that shows what colors go to what. Maybe you can splice the rears in and double check those front connections.

If you have power to the radio but no sound, check the wire that sends the signal to the amp. If none of the speakers are working, it sounds like the wire that sends the signal to the amp is not bridged over.

[@TheKeymaster316]

@ no worries. I’ve never been that great at the whole KZbin thing, it takes an incredible amount of time to video something and then try to explain it, so I have mad respect for the folks that have good channels because I know how difficult it is to make bad videos, so it really has to be hard to make the good ones. 😅. Most of the how-to videos I share happen because I have already figured out what I wanted to do and then decide, at the last minute, to make a quick video. But man, when there’s no written script, I really tend to beat around the bush. Sometimes it’s hard to go back and watch my old videos because I can see where the criticism comes from. Bad thing is, I sold this car about 5 years ago, so this video is all I have left. That factory amp really does make the aftermarket radio sound like crap, so if you can bypass it, it definitely helps!
